• Curiouser and curiouser becomes l'affaire Tooting where a domain address similar to that owned by Susan John-Richards, an independent candidate in south London, is known to have been appropriated and fiddled with so visitors are presented with the website of Mark Clarke, her former colleague – and now her Tory rival for the parliamentary seat. We raised this matter on Friday, and in the hours that followed two things happened. The first was that an angry reader reported the matter to the Electoral Commission. "This is unfair practice," he said in an email to the Tory. "I thought that the 'nasty' party was supposed to have disappeared. Clearly not." The second was that Clarke spoke out to protest his innocence. "Your allegation that I have hijacked the site or domain name is wholly untrue," he told the complainant. "If you read the Guardian article it made no allegation of any involvement by me. It's nothing to do with me. I don't own the domain name, have not requested the redirect, and I couldn't stop it if I tried. I have nothing to do with it." And that is no doubt right. Who on earth would want to benefit from such dirty tricks? Who would stoop so low?

• Because Cameroonies are for those who play fair and stick by the rules. But nobody knows what the rules are. How else to explain why so many Tories listed on the section of the party's website set aside for prospective candidates have been allowed to keep the title "MP" when the rules forbid it? "There are no Members of Parliament. Consequently you may not use that title during this period," says the official dissolution guidance. Gloves up in the blue corner, please. No low blows.

• And should Theresa May be watching her back a bit? With the prevailing wind, she should be able to do something with a 6,000 majority in Maidenhead. But the right doesn't seem to like the shadow secretary of state for work and pensions, and there is no obvious evidence that David Cameron rates her. There is clearly no downside to hurling a few insults her way. Witness Fraser Nelson, the well-connected editor of the Spectator, writing in the Telegraph on welfare reform. "The agenda died when Theresa May was sent in and Grayling was promoted to be shadow home secretary. With a nine-year track record of achieving precisely nothing in opposition, May is spectacularly ill-suited to what should be the toughest task in government." Nice friends you've got there, Theresa.

• More troubles in Toryland, as Jemima Khan (pictured) hits back at claims in the Telegraph that she is not being as supportive of her brother, Zac – the Conservative candidate for the west London seat of Richmond Park – as she might be. "Voting Tory is a bit like reading horoscopes. Millions do it but no one likes to admit to it," she tweeted last week, comments seized upon by the paper. "Tim Walker – Stop stirring," she said, returning to the fray and upbraiding the Telegraph's columnist. "I am supporting my brother and would proudly vote for him if I were a Richmond constituent." Yes, voting Tory is "a bit like reading horoscopes". But one imagines it must be like many things, good or ill. Diary readers will have a few ideas – a bottle of champagne for the most inventive.

• These people cross us at their peril. There was Ulster Unionist Adrian Watson ready for battle in South Antrim as a joint UUP-Conservative candidate. But alas, after our Ireland correspondent reminded everyone that Watson once publicly stated that he would bar gay people from staying in his family-run B&B and that people from the Travelling community were "scum", the Tory high command took fright and urged the UUP leadership to block Watson's candidacy. Poor Adrian, there he is now, supplanted as candidate by Ulster Unionist leader Sir Reg Empey and reduced to denouncing the Guardian on the Ulster airwaves. That it should end like this.
